Objective To explore the risk factors of children with cerebral palsy during pregnancy and neonatal period in Xinxiang area.Methods A retrospective analysis of the relevant research data of cerebral palsy children in Xinxiang area was performed.The research objects were children with cerebral palsy born from May 1,2005 to April 30,2010.At the same time,3 healthy children were selected as the control group to analyze the related risk factors causing cerebral palsy in children.Results The risk factors of children with cerebral palsy in Xinxiang city were as follows : maternal nutritional status, vaginal bleeding during pregnancy, pregnancy-induced hypertension syndrome, and abnormal production history were associated with cerebral palsy (x2 =2.313,13.296,5.034,7.434, all P ＜ 0.05)during the perinatal period;related factors during neonatal period were premature birth,severe asphyxia, severe jaundice, and intracranial infection(x2 =4.637,29.50,4.633,5.107, all P ＜ 0.05).Multivariate Logistic regression analysis showed the history of severe asphyxia (OR =2.340,95 ％ CI: 1.250-4.440), severe jaundice (OR =4.110, 95％ CI:2.430-6.740) ,premature birth(OR =2.570,95％ CI: 1.410-4.770) ,pregnancy-induced hypertension syndrome (OR =2.350,95 ％ CI:I.020-5.440), vaginal bleeding during pregnancy (OR =73.600,95 ％ C1:3.060-17.750) and abnormal production history(OR =5.710,95％ CI: 1.250-26.310) were independent risk factors causing children with cerebral palsy.Conclusions The history of severe asphyxia, severe jaundice, premature birth, pregnancy-induced hypertension syndrome, vaginal bleeding during pregnancy and congenital dysplasia are independent risk factors of children with cerebral palsy in Xinxiang area.It should be strengthened to screen and standardize the management of high-risk newborn infants with cerebral palsy, and do well management for perinatal high-risk pregnant women management.Early prevention can help to reduce the incidences of cerebral palsy in local area.

Objective To provide the nurse care evidence of nutritional intervention in patients with lung cancer during radiotherapy and chemotherapy by analyzing the nutritional status of these patients.Methods 55 patients with lung cancer who received chemotherapy and radiotherapy were selected.The nutritional status of these patients were evaluated by laboratory examination data at the time of hospitalized,ongoing and the end of radiotherapy. Results The hemoglobin(Hb),albumin(ALB),body mass and body mass index(BMI)were (130.50 ±17.80)g/L, (41.02 ±5.68)g/L,(61.29 ±8.75)kg,(22.36 ±2.78)kg/m2 respectively at admission;(115.90 ±19.00)g/L, (37.94 ±5.55)g/L,(59.95 ±9.05 )kg,(21.86 ±2.86)kg/m2 respectively during the course of radiotherapy;(110.40 ±19.40)g/L,(36.91 ±5.30)g/L,(58.91 ±9.30)kg,(21.48 ±2.99)kg/m2 respectively at the end of radiotherapy.At different stages of radiotherapy,the nutritional index gradually decreased,the Hb was lower in the middle of the radiotherapy than on admission,the difference was significant(t =8.611,P <0.05).The Hb in the late stage of radiotherapy was lower than the middle,the difference was significant(t =2.492,P <0.05).Although the ALB in the latter stage of radiotherapy was lower than the middle,but the difference was not statistically significant (t =1.464,P >0.05),and the difference was significant compared with on admission(t =4.815,P <0.05).The weight of the patients in the middle period of radiotherapy was less than the time of admission,but the difference was not statistically significant(t =0.781,P >0.05).The weight of patients in the late stage of radiotherapy was lower than the medium term,but the difference was not statistically significant as well(t =0.601,P >0.05),and there was no significant difference compared with on admission(t =1.382,P >0.05).The BMI of the patients with radiotherapy was lower than that at the time of admission,the difference was not statistically significant(t =0.091,P >0.05).The BMI of patients with radiotherapy was lower than that in the medium term,whereas the difference was not statistically significant(t =0.690,P >0.05),and the difference was not statistically significant compared with on admission(t =1.599,P >0.05).The Hb (F =16.643,P =0.000)and ALB(F =7.736,P =0.001)decreased significantly in particular.Conclusion The risk of malnutrition in patients with lung cancer is exist during radiotherapy and chemo-therapy,and it is obvious in the middle -late stage,the changes of physical and biochemical indexes have been appeared,and among them,Hb and ALB are the most obvious,so should be monitored and managed cause these data varied significantly.

Objective To evaluate the short-and long-term outcomes of laparoscopy-assisted gastrectomy (LAG) for gastric cancer.Methods After studying the patients' demographic data,extent of gastrectomy and lymphadenectomy,as well as differentiation and tumor TNM stage,85 patients who underwent LAG were individually matched to 85 patients who underwent open surgery (OG) between October 2004 and March 2008.The operative time,intraoperative blood loss,postoperative recovery,complications,pathological findings,and follow-up data were compared between the two groups.Results The mean operative time was significantly longer in the LAG group than in the OG group (277 ± 62) min vs.(211 ±46) min,t =7.882,P ＜0.05,whereas intraoperative blood loss was significantly lower (161 ±90) ml vs.(267 ± 141) ml,t =-5.854,P ＜0.05.In addition,there was a significant reduction in the time to first flatus and postoperative hospital stay (3.7 ± 1.3) days vs.(4.2 ± 1.1) days and (10 ± 3) days vs.(12 ± 6) days,respectively t =-2.318,-2.325,P ＜ 0.05.There was no significant difference between the LAG group and OG group with regard to the number of harvested lymph nodes and overall postoperative complications.The 5-year disease-free survival rates and overall survival rates were 76％,78％,respectively,in LAG group and 75％,73％,respectively in OG group (all P ＞ 0.05).Conclusions LAG is suitable and minimally invasive for treating gastric cancer.Compared to OG,the LAG will not increase the risk of recurrence and mortality after surgery.

Objective:To compare the changes in functional optical zone (FOZ) and corneal morphology in myopes between femtosecond small incision laser lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK).Methods:A cohort study was performed.A total of 94 patients (94 eyes) who underwent FS-LASIK or SMILE at Eye Hospital, Wenzhou Medical University from March to December 2021 were enrolled.The selected patients were divided into a SMILE group (46 cases, 46 eyes) and an FS-LASIK group (48 cases, 48 eyes) according to the surgical procedure, and the follow-up period was 6 months.The primary outcome measures were postoperative changes in corneal FOZ and Q-value, and the secondary outcome measures were changes in central corneal thickness (CCT) and mean corneal curvature (Km). Corneal Q-value, horizontal and vertical FOZ diameters, CCT, and Km were recorded before surgery and at 1 day, 1 week, 1 month, and 6 months after surgery using the Pentacam anterior segment analysis system, and the differences in each parameter and the trends of changes between the two groups were compared.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Eye Hospital, Wenzhou Medical University (No.2021-034-k-27). Written informed consent was obtained from each subject.Results:There were statistically significant overall differences in the postoperative horizontal and vertical FOZ diameters between the two groups (horizontal diameter: Fgroup=7.06, P<0.001; Ftime=64.18, P=0.001; vertical diameter: Fgroup=11.08, P<0.001; Ftime=77.14, P<0.001). The horizontal and vertical FOZ diameters were significantly larger in SMILE group than in FS-LASIK group at various postoperative time points, and the differences were statistically significant (all at P<0.001). In the two groups, the postoperative 1-week, 1-month and 6-month horizontal FOZ diameters and the postoperative 1-week and 1-month vertical FOZ diameters were smaller than the postoperative 1-day ones, and the differences were statistically significant (all at P<0.05). There were significant overall differences in Q-values at different postoperative time points between the two groups ( Fgrouup=53.11, P=0.019; Ftime=29.18, P<0.001). The postoperative 1-day, 1-week, and 1-month Q-values of FS-LASIK group were significantly higher than those of SMILE group (all at P<0.05). The postoperative 1-week Q-value was significantly larger than the postoperative 1-day value in SMILE group ( P<0.001). The postoperative Q-values gradually decreased with time in FS-LASIK group, with significant pairwise differences at all adjacent time points (all at P<0.001). There were significant differences in CCT at various postoperative time points between the two groups ( Ftime=21.43, P<0.01). In FS-LASIK group, the CCT was decreased at 1 week than 1 day after surgery and was increased at 6 months than 1 week after surgery, and the differences were statistically significant (all at P<0.05). In SMILE group, the postoperative 1-week, 1-month and 6-month CCT was increased in comparison with the postoperative 1-day value, and the differences were statistically significant (all at P<0.05). There was no significant overall difference in the Km between the two groups ( Fgroup=27.29, P=0.41). There were significant pairwise differences in the Km at different postoperative time points between the two groups (all at P<0.001). The postoperative 6-month Km was smaller than the postoperative 1-day value in SMILE group, and the postoperative 6-month Km was greater than the postoperative 1-day value in FS-LASIK group (both at P<0.05). Conclusions:The FOZ shows a trend of gradual reduction within a month after SMILE and FS-LASIK.The FOZ is larger after SMILE than after FS-LASIK.The morphologic stability of corneal FOZ is better after SMILE than after FS-LASIK.

OBJECTIVETo investigate the epidemiology, internal opening location, and risk factors associated with recurrence of anal fistula.

METHODSClinical data of 1783 hospitalized patients admitted for anal fistula treatment to Shanghai Shuguang Hospital from January 2013 to September 2015 were retrospectively analyzed. Fistula passing through anorectal ring or locating above was defined as high anal fistula (n=125). Internal opening location was defined as follows: posterior (5 to 7 o'clock), front(11 to 1 o'clock), left (2 to 4 o'clock) and right (8 to 10 o'clock).

RESULTSAmong 1783 cases, 1526 were male with a median age of 36 years, 257 were female with a median age of 35 years, and the ratio of male to female was 5.9 vs 1.0. In high anal fistula cases, this ratio of male to female was 7.3 vs 1.0. Posterior internal opening accounted for 51.4%(884/1720), while this percentage was 66.4%(83/125) in high anal fistula cases, which was significantly higher than 50.2%(801/1595) in low anal fistula cases(P=0.002). Postoperative recurrence rate was 2.6%(45/1720) and the rates in high anal fistula and low anal fistula were 13.6%(17/125) and 1.8%(28/1595) respectively, with significant difference(P=0.000). Multivariate logistic regression analysis showed that fistula height(OR=5.475, 95%CI:2.230 to 13.445, P=0.000), treatment history(OR=2.671, 95% CI:1.315 to 5.424, P=0.007), seton placement history (OR=4.707, 95%CI:1.675 to 13.232, P=0.003) and concomitant colitis(OR=10.300, 95%CI:1.187 to 89.412, P=0.034) were independent risk factors for anal fistula recurrence. Seton placement history was an independent risk factor for high anal fistula recurrence (OR=6.476, 95%CI:1.116 to 37.589, P=0.037).

CONCLUSIONSAnal fistula occurs in young and middle-aged male patient. Internal opening locates in posterior more commonly, especially in high anal fistula patients. Postoperative recurrence rate of high anal fistula is quite high. Patient with both high anal fistula and seton placement history has significantly high rate of postoperative recurrence.

Objective:To develop a risk prediction model for the recurrence of diabetic foot ulcer (DFU) in diabetic patients and primarily validate its predictive value.Methods:Meta-analysis combined with retrospective cohort study was conducted. The Chinese and English papers on risk factors related to DFU recurrence publicly published in China Biology Medicine disc, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and PubMed, Embase, Cochrane Library, and Web of Science, and the search time was from the establishment date of each database until March 31 st, 2022. The papers were screened and evaluated, the data were extracted, a meta-analysis was performed using RevMan 5.4.1 statistical software to screen risk factors for DFU recurrence, and Egger's linear regression was used to assess the publication bias of the study results. Risk factors for DFU recurrence mentioned in ≥3 studies and with statistically significant differences in the meta-analysis were selected as the independent variables to develop a logistic regression model for risk prediction of DFU recurrence. The medical records of 101 patients with DFU who met the inclusion criteria and were admitted to Affiliated Hospital of Guizhou Medical University from January 2019 to June 2022 were collected. There were 69 males and 32 females, aged (63±14) years. The receiver operating characteristic (ROC) curve of the predictive performance of the above constructed predictive model for DFU recurrence was drawn, and the area under the ROC curve, maximum Youden index, and sensitivity and specificity at the point were calculated. Dataset including data of 8 risk factors for DFU recurrence and the DFU recurrence rates of 10 000 cases was simulated using RStudio software and a scatter plot was drawn to determine two probabilities for risk division of DFU recurrence. Using the β coefficients corresponding to 8 DFU recurrence risk factors ×10 and taking the integer as the score of coefficient weight of each risk factor, the total score was obtained by summing up, and the cutoff scores for risk level division were calculated based on the total score × two probabilities for risk division of DFU recurrence. Results:Finally, 20 papers were included, including 3 case-control studies and 17 cohort studies, with a total of 4 238 cases and DFU recurrence rate of 22.7% to 71.2%. Meta-analysis showed that glycosylated hemoglobin >7.5% and with plantar ulcer, diabetic peripheral neuropathy, diabetic peripheral vascular disease, smoking, osteomyelitis, history of amputation/toe amputation, and multidrug-resistant bacterial infection were risk factors for the recurrence of DFU (with odds ratios of 3.27, 3.66, 4.05, 3.94, 1.98, 7.17, 11.96, 3.61, 95% confidence intervals of 2.79-3.84, 2.06-6.50, 2.50-6.58, 2.65-5.84, 1.65-2.38, 2.29-22.47, 4.60-31.14, 3.13-4.17, respectively, P<0.05). There were no statistically significant differences in publication biases of diabetic peripheral neuropathy, diabetic peripheral vascular disease, glycosylated hemoglobin >7.5%, plantar ulcer, smoking, multidrug-resistant bacterial infection, or osteomyelitis ( P>0.05), but there was a statistically significant difference in the publication bias of amputation/toe amputation ( t=-30.39, P<0.05). The area under the ROC curve of the predictive model was 0.81 (with 95% confidence interval of 0.71-0.91) and the maximum Youden index was 0.59, at which the sensitivity was 72% and the specificity was 86%. Ultimately, 29.0% and 44.8% were identified respectively as the cutoff for dividing the probability of low risk and medium risk, and medium risk and high risk for DFU recurrence, while the corresponding total scores of low, medium, and high risks of DFU recurrence were <37, 37-57, and 58-118, respectively. Conclusions:Eight risk factors for DFU recurrence are screened through meta-analysis and the risk prediction model for DFU recurrence is developed, which has moderate predictive accuracy and can provide guidance for healthcare workers to take interventions for patient with DFU recurrence risk.

Objective To summarize and explore the current state,hotspots,and trends in the field of surgical treatment for intracerebral hemorrhage(ICH)over the past decade through a bibliometric and visualization analysis of relevant literature.Methods Relevant Chinese and English literature on the surgical treatment of ICH,published from January 1,2014 to April 1,2024,was retrieved and screened from CNKI and Web of Science databases.Visualization analysis was conducted using CiteSpace,VOSviewer,and other software to analyze the number of published papers,authors,countries,institutions,etc.Social network analysis diagrams of authors,keyword clustering network analysis diagrams,keyword burst strength,and keyword timeline maps were also utilized.Results(1)A total of 3 456 relevant papers were included,with 2 173 in Chinese and 1 283 in English.From 2014 to 2021,the annual number of Chinese publications on ICH surgery was higher than that of English publications,but the number of Chinese publications began to decline from 2016.The number of English publications showed an overall increasing trend.(2)A total of 6 367 authors were identified from the English literature,with notable collaboration networks led by researchers such as Mocco J,Hanley DF,Ziai WC,You C,and Tang ZP.The Chinese literature included 6 522authors,with prominent collaboration networks led by Wang LK,Cai Q,Ku HB,Zhang S,and Zhu SQ.(3)Analysis of the countries involved in the English literature showed that 31 countries participated in research on ICH surgery,with China leading in the number of publications(505),followed by the United States(330)and Germany(106).The top three countries in centrality were the United States(0.32),China(0.16),and Canada(0.11).The top three institutions in English literature publications were Johns Hopkins University(51 papers),Ohio State University(39 papers),and Harvard University(38 papers).In China,Sichuan University(32 papers),Huazhong University of Science and Technology(30 papers),and Capital Medical University(27 papers)had multiple English publications;Wuhan University People's Hospital(15 papers),Affiliated Hospital of Guizhou Medical University(13 papers),and Affiliated Hospital of Yan'an University(13 papers)had multiple Chinese publications.There was close collaboration among research institutions in the English literature,whereas Chinese researchers often established research teams within their medical units with relatively less collaboration between teams.(4)Research on ICH surgery primarily focused on surgical methods,complications,and comprehensive perioperative treatment.Research hotspots included hypertensive ICH,minimally invasive surgical techniques,and perioperative management and treatment."neuroendoscopy"was the most recent emergent keyword in Chinese literature with high centrality and the strongest burst strength,while"randomized trial"had the highest burst strength in English literature.Research trends included the integration of artificial intelligence with minimally invasive techniques to optimize ICH surgery management and treatment strategies,analysis of risk factors,and evaluation of imaging value.Conclusions Over the past decade,the overall publication volume on the surgical treatment of ICH has been in a stable development phase,with research directions covering surgical techniques,diagnosis and treatment,evaluation,and management.Core research teams led by key authors were the main contributors to the publications.Future research hotspots and trends in ICH surgery may include the optimization of surgical techniques,complication management,large-scale multicenter clinical trials and integration of artificial intelligence with minimally invasive techniques.

Objective:To investigate the clinical and imaging features of population receiving opportunistic screening for lung cancer and in convalescent stage of COVID-19.Methods:Cross-sectional study and analysis was performed on the patients who underwent chest low-dose CT examination for cancer prevention in Cancer Hospital of Chinese Academy of Medical Sciences from December 28, 2022 to January 19, 2023. All the patients completed the COVID-19 questionnaire. A total of 334 questionnaires were sent out, all of which were recovered, and 321 valid questionnaires were collected, among them, 293 questionnaires were included in the analysis. Statistical analysis was conducted according to the questionnaire information, clinical symptoms and chest CT imaging results. The potential influencing factors of COVID-19 infection were explored, and the imaging characteristics of COVID-19 infection and early stage of lung cancer were compared.Results:A total of 293 patients underwent lung cancer screening during the convalescent stage of COVID-19 infection. A total of 231 (78.8%) cases had cough and 228 (77.8%) cases had fever. 214 (73.0%) cases still had clinical symptoms within 2 weeks after nucleic acid or antigen test showing negative, especially for cough in 171 (58.4%) cases, fatigue in 79 (25.3%) cases and sputum in 73 (24.9%) cases. There were 54 (18.4%) cases with positive chest CT changes. The main imaging findings showed that there were 46 cases with new patchy shadows, 25 cases with linear opacities, 10 cases with ground-glass opacities, 10 cases with nodular like shadows and 2 cases with consolidation, and most lesions were in the subpleural area of both lungs. Univariate analysis showed that positive CT findings were correlated with the time from positive detection of COVID-19 to screening ( P=0.026), age ( P<0.001) and underlying diseases ( P=0.006). Multivariate analysis showed that age≥65 years old ( OR=6.425, 95% CI: 2.688-15.358; P<0.001) and underlying diseases ( OR=2.292, 95% CI: 1.120-4.691; P=0.023) were risk factors for pulmonary imaging changes of COVID-19 infection. For lung cancer opportunistic screening, 36 (12.3%) cases showed ground-glass opacities in bilateral or unilateral lung lobes, among which 4 cases were suspected to be atypical adenomatous hyperplasia and 2 cases s were suspected to be early stage of lung cancer. Conclusions:Abnormal clinical symptoms and chest CT findings are still observed in the patients during the convalescent stage of COVID-19 infection. Age≥65 years, underlying diseases were the high-risk factors for the changes in chest CT imaging after COVID-19 infection. Attention should be paid to the differential diagnosis of chest CT findings between changes in the convalescent stage of COVID-19 and early stage of lung cancer.
